    Sort of off-topic question: how did the cd sampling rate of 44.1 kHz get chosen? If the desired frequency response was up to 20kHz, then why not a 40kHz

      Sort of off-topic question: how did the cd sampling rate of 44.1 kHz get
      chosen? If the desired frequency response was up to 20kHz, then why not a
      40kHz sampling rate?

      Maybe the following has something to do with it? Or is it just a wierd
      coincidence?

      1x2x3x5x7 = 210
      210 ^ 2 = 44100

      :D
